Information on the data input is transferred to the Q-output on the LOW-to-HIGH transition of the clock pulse. The D-input must be stable one set-up time prior to the LOW to HIGH clock transition for predictable operation. Inputs can be driven from either 3.3 V or 5 V devices. This feature allows the use of this device in a mixed 3.3 V and 5 V environment. This device is fully specified for partial power-down applications using IOFF. The IOFF circuitry disables the output, preventing the damaging backflow current through the device when it is powered down. Wide supply voltage range from 1.65 V to 5.5 V High noise immunity Complies with JEDEC standard: JESD8-7 (1.65 V to 1.95 V) JESD8-5 (2.3 V to 2.7 V) JESD8B/JESD36 (2.7 V to 3.6 V) ESD protection: HBM JESD22-A114F exceeds 2000 V MM JESD22-A115-A exceeds 200 V 24 mA output drive (VCC = 3.0 V) CMOS low power consumption Latch-up performance exceeds 250 mA Direct interface with TTL levels Inputs accept voltages up to 5 V Multiple package options Specified from 40 C to +85 C and 40 C to +125 C.
